Matt Cappotelli, who previously proved his athletic prowess as a member of the Western Michigan University football team, quickly made a name for himself in sports-entertainment as a co-winner of WWE Tough Enough III.

He shared the victory in 2003 with John Hennigan, who later came to be known as John Morrison. After coming out on top of the WWE reality competition, the duo quickly started their training in Ohio Valley Wrestling to become future Superstars.

Cappotelli’s OVW training was cut short in 2006 due to an initial brain cancer diagnosis that was treated one year later. Ten years after surviving the first battle, his cancer resurfaced in 2017 and worsened later in the year.

In 2017, Cappotelli spoke with WWE.com about his second bout with cancer. Despite the troubling outlook, he continued to publicly fight his illness in hopes his story might help others find the strength to keep fighting their battles, too.

Morrison was one of many Superstars to express his grief over Cappotelli’s passing on social media.

Other Superstars also shared their memories and condolences:

Rest easy my friend. So grateful that I had the opportunity to know you. To laugh with you. To make so many memories in @ovwrestling together with you. They say only the good die young. That rings all to true with you. You heart belongs with the angels. Xoxo #RIPCap#CuteBootshttps://t.co/85veye9EsX
